Re: gtktable question

[Tristan Van Berkom <vantr touchtunes com>]

I'm not familiar with a GtkTable, but
a a GtkTable is an implementation of
GtkContainer. so:

GTK_CONTAINER(table)->remove(GTK_CONTAINER(table), child_widget);

should be more apropriate than removeing it by hand
from the GList.

(this would be the equivalent of calling:
"gtk_container_remove(GTK_CONTAINER(table), child_widget);"
because container will call the objects implementation of "remove")

NOTE:
remember that if the container didn't create the widget;
removing it will not bring the reference count to 0; so that
widget will not be finalized. (you can still use a widget that
has been added/ref'd --> removed/unref'd)


also you might want to check what happens when you call
gtk_container_add(GTK_CONTAINER(table), child_widget);

and check the "GtkContainer" documentation for more funky
stuff that "containers" implement ... such as:

gtk_container_resize_children()
gtk_container_forall()
etc etc...

=========================

if you really need to "manhandle" the widget you might try

gtk_widget_queue_draw(GTK_WIDGET(table));

at the end and let the event loop do its thing
        _or_
copy the source of the GtkTable in order to make one
that does what you want.

But I really doubt that a widget as seemingly generic
as the table doesn't support at least 
removing / repositioning / resizing.
